If you are searching for OUAC 101 vs 105, the terminology has changed. OUAC now uses one smart Undergraduate application and classifies applicants as Group A or Group B. This guide translates the old labels and explains the current process.
Group A (formerly OUAC 101)
OUAC assigns Group A when an applicant meets all three current criteria involving Ontario high school course enrollment, age, and an OSSD with six 4U/M courses. The exact date window and age cut-off change by admission cycle, so verify them in the current Undergraduate Application Guide.
How Group A works
The current application asks for your Ontario Education Number and uses your responses to place you in the correct group. Ontario schools provide grades to OUAC, and the base application fee covers your first three program choices. Read our Getting Started guide for the full step-by-step walkthrough.
Group B (formerly OUAC 105)
If you do not meet every Group A criterion, the smart application places you in Group B. This includes many applicants previously described as 105 applicants.
Common Group B applicants
Common examples are Canadians studying outside Ontario, former Ontario high school students, postsecondary transfer students, mature students, and international applicants. Transcript, document, and deadline requirements vary by background and university.
International applicants
International applicants are generally Group B. Depending on the university and educational background, supporting requirements may include transcripts, translations, proof of English proficiency, and later immigration documentation. Apply early enough for each institution to receive and review the required files. Our International Student Guide covers study permits and document requirements in detail.
Fees and Deadlines
For 2026, OUAC lists a $156 base fee for the first three program choices and $50 for each additional choice. Other international, program, transcript, or document evaluation fees may apply, so review the itemized fee page before payment.
The Group A deadline for 2027 entry is January 15, 2027. Group B does not have one universal OUAC deadline; dates vary by institution and program. Document, portfolio, interview, and supplementary-form deadlines can also differ. New to the process? Use our Ontario university application deadline guide to track the full 2027 timeline. Then start with Getting Started and check the Academic Requirements chapter for prerequisites and average calculations.
Common Mistakes to Avoid
The smart application now assigns your group, reducing the risk of selecting the wrong form. The remaining common mistakes are missing program-specific deadlines, leaving university portals incomplete, choosing the wrong program code, and not monitoring email. After submission, keep your OUAC Reference Number and check each university portal regularly.
